Previous research has demonstrated the importance of both dynamic and isometric maximal strength and rate of force development (RFD) in athletic populations. The purpose of this study was to examine the relationships between measures of isometric force (PF), RFD, jump performance and strength in collegiate football athletes. The subjects in this study were twenty-two men [(mean ± SD):age 18.4 ± 0.7 years; height 1.88 ± 0.07 m; mass 107.6 ± 22.9 kg] who were Division I college football players. They were tested for PF using the isometric mid thigh pull exercise. Explosive strength was measured as RFD from the isometric force-time curve. The one repetition maximum (1RM) for the squat, bench press and power clean exercises were determined as measures of dynamic strength. The two repetition maximum (2RM) for the split jerk was also determined. Vertical jump height and broad jump was measured to provide an indication of explosive muscular power. There were strong to very strong correlations between measures of PF and 1RM (r = 0. 61 - 0.72, p < 0.05). The correlations were very strong between the power clean 1RM and squat 1RM (r = 0.90, p < 0.05). There were very strong correlations between 2RM split jerk and clean 1RM (r = 0.71, p < 0.05), squat 1RM (r = 0.71, p < 0.05), bench 1RM (r = 0.70, p < 0.05) and PF (r = 0.72, p < 0.05). There were no significant correlations with RFD. The isometric mid thigh pull test does correlate well with 1RM testing in college football players. RFD does not appear to correlate as well with other measures. The isometric mid thigh pull provides an efficient method for assessing isometric strength in athletes. This measure also provides a strong indication of dynamic performance in this population. Key pointsIn Division I college football players the isometric mid thigh pull test correlates well with 1RM testing.Rate of Force Development does not appear to be as closely related to dynamic and isometric strength in college football players.The isometric mid thigh pull provides a quick and efficient method for assessing isometric strength in athletes.
先前的研究已经证明了动态和等长最大力量以及力的发展速率（RFD）在运动员群体中的重要性。本研究的目的是检验等长力（PF）、RFD、跳跃表现和力量在大学生足球运动员中的关系。本研究的受试者为 22 名男子[（平均值±标准差）：年龄 18.4±0.7 岁；身高 1.88±0.07 米；体重 107.6±22.9 公斤]，他们是一级大学足球运动员。他们接受了等长大腿中部拉伸运动的 PF 测试。爆发力强度通过等长力-时间曲线的 RFD 来测量。深蹲、卧推和力量清洁练习的一次重复最大（1RM）被确定为动态强度的测量。分裂挺举的两次重复最大（2RM）也被确定。垂直跳跃高度和跳远用于提供爆发力的指示。PF 和 1RM（r = 0.61-0.72，p<0.05）之间存在强到非常强的相关性。功率清洁 1RM 和深蹲 1RM 之间的相关性非常强（r = 0.90，p<0.05）。2RM 分裂挺举和清洁 1RM（r = 0.71，p<0.05）、深蹲 1RM（r = 0.71，p<0.05）、卧推 1RM（r = 0.70，p<0.05）和 PF（r = 0.72，p<0.05）之间存在很强的相关性。与 RFD 没有显著相关性。等长大腿中部拉伸测试与大学生足球运动员的 1RM 测试相关性良好。RFD 似乎与其他测量结果的相关性不如 1RM 那么好。等长大腿中部拉伸为运动员的等长力量提供了一种有效的评估方法。在这个群体中，这种测量方法也强烈表明了动态表现。关键点在一级大学足球运动员中，等长大腿中部拉伸测试与 1RM 测试相关性良好。在大学生足球运动员中，力的发展速率似乎与动态和等长力量的关系不如 1RM 那么密切。等长大腿中部拉伸为运动员的等长力量提供了一种快速有效的评估方法。
